When trying to assign a regular string literal to an Objective-C 'id' type or a pointer to an NSString, emit a code insertion hint that turns it into an Objective-C string. For example:

@class NSString;

@interface Test
+ (void)test:(NSString *)string;
@end

void g(NSString *a);

void f() {
  NSString *a = "Foo";
  g("Foo");
  [Test test:"Foo"];
}

will produce

t.m:10:17: warning: incompatible pointer types initializing 'char [4]', expected 'NSString *'
  NSString *a = "Foo";
                ^~~~~
                @
t.m:11:5: warning: incompatible pointer types passing 'char [4]', expected 'NSString *'

and implicitly defined constructors.  This has a number of benefits:

1. Less code.

2. Explicit and implicit constructors get the same diagnostics.

3. The AST explicitly contains constructor calls from implicit default
constructors.  This allows handing some cases that previously weren't handled
correctly in IRGen without any additional code. Specifically, implicit default
constructors containing calls to constructors with default arguments are now
handled correctly.
